A limited outbreak of Ebola haemorrhagic fever in Etoumbi, Republic of Congo, 2005

Abstract

Ebolavirus has caused highly lethal outbreaks of haemorrhagic fever in the Congo basin. The 2005 outbreak in the Republic of Congo occurred in the Etoumbi district of Cuvette Ouest Department between April and May. The two index cases were infected while poaching. The sanitary response consisted of active surveillance and contact tracing, public awareness campaigns and community mobilization, case management and safe burial practices, and laboratory confirmation. Twelve cases and ten deaths were reported (lethality 83%). A transmission tree was constructed from a sample collected by a medical team. This outbreak was remarkable by its short duration and limited size. Increased awareness among these previously affected populations and the rapid response of the healthcare system probably contributed to its extinction
